ALFRED 'srELL, or s'rEEToN, NEAR KEIGHLEY, A D JOHN STELL WELCH ASSIGNOR To sun 0F KEIGHLEY, ENGLAND; SAIID SAID JOHN STELL.

To all whom it may concern Be it known that we, ALFR D STELL, JOHN STELL, and HENRY WELCH, King of Great Britain, and residents, respectively, of Greenhill, Steeton, near Keigh- -ley,1n the county of York, England, Devonshire street, Keighley, aforesaid, and 25' yarns onthreads so secured that the spinmng or like operations maybe re-started.

Our present invention consists in the ap-- plication of improved parts to the type or class of mechanism described in the United States Patent'specification No. 995565, such application of improved parts having for its object the carrying outwith greater efliciency the process of removing the full bobbins and substituting empty bobbins in their place. The devices which we employ are illustrated in the accompanying sheets of drawings wherein M Figure 1 is'an end elevation'of a suflicient portion of a spinning frame to illustrate the application thereto of our improvements. Fig. 2 is a front elevation of parts shown by Fig. 1. Fig. 3 is' a sectional erml elevation of a porition of..a spinning frame having our improvements applied thereto, the different parts thereof being shown in the positions they occupy during the spinning operations.

Fig. 4 is a similar View to Fig. 3 and shows the parts in position afterthe first part of the dofling operations has been performed, that is, when the caps have been'raised by the spindles and returned by their holders. Fig. 5 is also a similar view to Fig. 3 and illustratesthe positions which the several parts occupy when the spindles have been lowered clear of the caps with the caps drawn away, thefull bobbins held upon eir spindles and the parts for the reception Specification of Letters Patent.

of the full bobbins ready to be placed into pos1t1on to receive them. Fig. 6 is also a sectional end elevation and shows theparts in their positions when the full bobbins have been removed and the empty bobbins have been adjusted in position for being lowered upon the splndles. Fig. 7 is a front elevation of a device for receiving and moving the full and empty bobbins. Fig. 8 is a plan thereof. Fig. .9 is a view as seen in the direction at right angles to Fig. 7.

A indicates the end frame of the machine B, B the upper and lower fixed rails of the machine,

The spindle rail 1 is mounted upon the vertical racks 2 which pass through and are guided by the fixed rail B. The said rail 1 supports the spindles 3 upon which, are mounted the caps 4. irls 5 rotate the bobbins 6 which takeover tubes 7 in the usual manner. The racks 2 are raisedand lowered by means of the pinions 9 which are fixed upon the shaft '9 the latter being carried in bearings 10 supported by the rail B.

The shaft 9 is rotated by the hand wheel 11 through the gear wheels 12 and 13 in manner well knowne and C, C the front rollers thereof.

Carried by the bearings 10 is another shaft 1 ions 19 which gear with racks 21 moving in the brackets 17. The racks 22 upon whichare mounted 21 support a bar brackets 23 such brackets supporting the shaft 24, lever arms 25 on which carry the bar 26, this latter acting as a thread-holding device in manner hereinafter described.

Supported'by the bracket 23 and in proximity to the bar 22 is another bar 27 which has mounted upon it racks 28, these latter gearing with pinions 29 which are free to rotate. upon'studs 30 mounted upon the plate 22. The pinions 29'support plates 31 upon which are mounted the semi-circular supporting tubes or half tubes 32, 33, which are approximately of the same diameter as the interior of a bobbin 6.

tubes have to be placed in spindles 3 in the mannerhereinafter-"de scribed, and in order-.toenablethem to ac- These supporting contact with the commodate, toi sl ight irregularitheir ends 47 turned at ties in the sizes or positions of said'spindles we arrange springs 34, '35, to intervene between the plate 36, which is fixed to the pinion 29, and the downwardly extending parts 37, 38 of the plate 31.- A

Mountedin bearings 39 are racks 40 which are reciprocated by toothed quadrants 41, fixed upon the shaft 42, these being operated by the handle 43 in manner well known. The racks 40 carry a plate 42 upon which are mounted a series of bifurcated holders 43 which are for the purpose of laying hold of and moving the caps 4 in manner well understood.

In brackets 44 carried by the plate 42 (or in fixed bearings or bearings which will allow vertical movement) is a shaft 45 upon which are mounted spring arms 46 having an angle and if desired having their points sharpened. This shaft 45 is oscillated by the handle 48 and 15 for the purpose of taking beneath the full bobbins 6 or empty bobbins 6 somewhat in the manner as shown byFig. 5, or the points the lower ends of the caps 17 carrying the bar 22 mounted the plates 31 are rotated by their pinions, .bobbms 6' to be moved away:

ofthe ends 47 may be pressed or dug into the yarn on the bobbins.

To carry out the process of dofling the operations of our improved apparatus are as folloWs:The caps 4 are raised by means of the spindlerail 1. into the .positionindicated by Fig. 4, after which the plate. 42 with the bifurcated supporting pieces 43 is advanced so that the pieces 43 pass beneath the flanges 4 on the caps 4;in -order to support said caps. The spindle rail 1 is then lowered to carry the spindles clear of 4. The brackets upon which are then raised and the racks 21 advanced so as to carry the b1- furcated ends of the plates 31'beneath the bottom flanges of the bobbins 6-so that they thus support said bobbins. The racks 40 are. then returned to their former positions so as to carry the caps away from the spindles and in'proximity to the rail B as shown by Fig. 5 The brackets 17 and consequently the plates 31 are then raised so as to carry the bobbins 6 suiiiciently above the ends 47 ofthe arms 46 in order to permit these to be moved beneath said bobbins 6 as shown by Fig. 5; The plates 31 are then, moved from beneath said'bobbins flanges the bob- 55' bins being then supported by the arms 46.

After this the'plates 31 are-slightly lowered and'advanced so that the half tubes 32 or a 33 take against the spindles 3 somewhat as shown by Fig. 8. The bobbins 6 are then released by the movements of the arms 46, hence said bobbins descend upon the half tubes 32. The plates 31 are thenraised until they are clear of theupp 'r en s 0 the spindles 3 so that theplate's 31' may 295-136 causethe full from-the spinhalf tubes -threads to be placed in proximity to the be i same out dles 3 and the empty bobbins which are supported by the half tubes 33 to be'carried vertically over said spindles. The-plates 31 are then lowered so as to move the empty bobbins somewhat into the position in which the full bobbin 6 is shownin Fig. 5, and the arms 46 moved so as to support same. The plates 31 are now to be lowered to a position where the half tubes 33 are clear of the lower ends of the bobbins 6*, on which said plates 31 are moved horizontally away from thespindles 3, so that the arms 46 may be moved to release the empty bobbin ,6 which then fall over or upon the tubes 7. The caps 4 are advanced to a position vertically over the spindles 3 which are then raised so as to carr the empty bobbins within 'them as well as to support said caps, after which the bifurcated holders 43 are returned to the position indicated by See Fig. 6.

Fig. 3, and the spindle rail moved into the spinning position. then moved b the upper en its arms so as to pass over 32 this movement causirf'g the notched plate 5 'on the upper end of the whirl 5 so that on the tubes 7 being restarted into action the threads are caught in the serrations in said flange 5 whereby such -threads are placed in their desired positions for the commencement of the. winding on the new set of'empty bobbins, the threads extending from the full "bobbins .being broken by being held by the notched bar or rod 26. p
